METHOD FOR MANUFACTURING OF FOAMING POLYETHYLENE TEREPHTHALATE SHEET MOLDING

摘要

PROBLEM TO BE SOLVED: To control cost concerning molding and to inhibit degradation of quality of a molding.

SOLUTION: A method for manufacturing of a foaming polyethylene terephthalate sheet molding includes: step S2 which performs heating to a condition in which a foaming polyethylene terephthalate sheet of high crystallinity is softened to be molded; and step S3 in which the foaming polyethylene terephthalate sheet of high crystallinity which has been heated to a condition to be softened to be molded is molded with a mold heated at a thermal deformation temperature and which performs molding of an inhibition section P2 which inhibits a force added to the molding section around a molding section P1 becoming a molding.
